Help me find this manhwa (or was it a webtoon?) please.

So it was a romance and all I remember is that the ML was super shy and had brown hair and yellow eyes.
He was mistaken for a girl sometimes.

The FL is like the silent, cold type but the better version of that troupe— anyway she had black hair and black eyes.
It was the popular x unpopular cliche.
